An unusual, one-off occurrence? Unfortunately not, indeed, it would appear that most large pharmaceutical drug companies have been caught publishing the 'science' they liked, and not publishing the 'science' the disliked! See this link, from my e-book 'The Failure of Conventional Medicine' for more examples of this illegal and unsafe practice.

Conventional medicine claims to be supported by an 'evidence base'. It would appear that some of this evidence base is actually fraudulent - and perhaps more of it than we are aware. That would certainly explain why so many pharmaceutical drugs, given to patients as tested, and therefore effective and safe, turn out to be ineffective and dangerous.
